INTRODUCTION: Endobronchial ultrasonography (EBUS)-guided fine-needle aspiration (FNA) is increasingly used to sample central lung lesions and mediastinal lymphadenopathy. We investigate the utility of EBUS-guided FNA and concomitant rapid on-site evaluation (ROSE) to diagnose granulomas, the morphologic characteristics of granulomas on ROSE, and how the diagnosis of granulomas changed the clinical impression.
MATERIALS AND METHODS: All pathologic reports and associated clinical records of patients who had EBUS-guided FNA of the lungs or mediastinal lymph nodes that yielded granulomas were reviewed with at least a 1-year follow-up after EBUS-guided FNA. All ROSE slides were rereviewed to evaluate granulomas for quantity, necrosis, and cohesion.
RESULTS: Over a 3-year period, 882 EBUS-guided FNAs were performed. One hundred and twelve patients (49% male, average age 50.8 years, range 16-83) had 161 EBUS-guided FNAs that yielded granulomas (18%). The etiologies of the granulomas were as follows: sarcoidosis (54%), infection (12%), malignancy (5%), inflammatory bowel disease-related lymphadenopathy (1%), and no specific clinical etiology (28%). Of the patients with EBUS-guided FNAs, 98 had ROSE performed (87.5%) and granulomas were seen in 70 of these patients (71%). Granulomas associated with sarcoidosis were mostly well-formed and non-necrotizing (90%). The results of the EBUS-guided FNA changed or redefined the clinical diagnosis in 79 patients (71%).
CONCLUSIONS: EBUS-guided FNA with concurrent ROSE is a useful technique for the diagnosis of granulomas. The quality and quantity of granulomas detected during ROSE may suggest an etiology and help direct ancillary testing.
